11. The hearing device of claim 1 , wherein: the biomarker feature analysis heuristic includes detecting biomarker features for indications for a neurodegenerative disease; and the processor is further configured to output a result of the biomarker feature analysis heuristic.

12. A hearing device configured to be worn by a user, the hearing device comprising: a microphone configured to detect an audio signal; a wireless interface configured to at least one of: receive incoming voice data from an additional device, and transmit own voice content representative of a voice of the user to the additional device; a processor communicatively coupled to the microphone and the wireless interface, the processor configured to: determine that the audio signal includes the own voice content during a first portion of the audio signal; determine that the own voice content is absent from the audio signal during a second portion of the audio signal when the wireless interface is receiving the incoming voice data; determine that an environmental noise level within the second portion of the audio signal is below an environmental noise level-related threshold; and apply, based on the determining that the environmental noise level is below the environmental noise level-related threshold, a biomarker feature analysis heuristic to the own voice content.

13. A method comprising: determining, by a hearing device configured to be worn by a user, that an audio signal received by the hearing device includes own voice content representative of a voice of the user; determining, by the hearing device, that an environmental noise level within the audio signal is below an environmental noise level-related threshold; and applying, by the hearing device, based on the determining that the environmental noise level is below the environmental noise level-related threshold, a biomarker feature analysis heuristic to the own voice content.
